To the Editor: The incidence of esophageal
and gastric cardia adenocarcinoma is increasing in Western Europe and the
United States.1 Survival rates2
are substantially improved by early tumor detection.3

and obesity5 were found to be strong independent

with reflux has been suggested,6 but the
benefits and efforts are unknown.
